In behavior analysis, which approach would you use to strengthen a behavior?

Strengthening a behavior in behavior analysis is best achieved through positive reinforcement. This approach involves presenting a favorable outcome or reward after the desired behavior is exhibited, which increases the likelihood that the behavior will be repeated in the future. For instance, if a student completes their homework and receives praise or a reward, the student is more likely to complete their homework again.

Positive reinforcement is grounded in the principles of operant conditioning, where behaviors are influenced by their consequences. By consistently applying rewards when the target behavior occurs, you create a positive association with the behavior, effectively reinforcing it.

While there are other methods such as negative reinforcement, which involves the removal of an aversive stimulus to increase a behavior, it is the addition of a positive consequence—rather than the removal of a negative one—that clearly strengthens behaviors in a straightforward and impactful manner.
